English 219. Putting into operation1. Before useBefore putting into operation,and especially after any repair work, check to see that all nuts and bolts are tight.ALWAyS disconnect the unlt from the air supply before carrylng out any repalr work.1. a) Mount the noule set tightlyAllgn the air nozzle so that the number stamped lnto it can be read from thefront the rlght wayround.b)Blow out the air hose before attaching it to the air connection (l/4“).(Air hose pressure-resistant.upto min. 10 bar and sol-vent-resistant. Total electric resistance:less than 100 million Ohm).c)The paint spray gun has been treated with an anticorrosive agent before leaving the factory and must therefore ge flushed outthoroughly with thinner before use.2. Adjusting the volume of air using the comprossed-air micrometerThe air supply can be regulated extremely fine to suit all operational conditions. Micrometer in vertical position (parallel to gunbody) = maximum atomization. Micrometer in horizontal position (across gun body) = minimum atomization (for blending, etc.)During Operation, never remove hollow screw by using the small hollow key in Order to remove the micrometer.3. Reduction of the material volumeThe volume of material flowing from the nozzle and thus the needle stroke can be reduced steplessly by screwing in the material-volume regulation screw.4. Changing the nozzlesetAlways Change the complete nozzle set whenever changing nozzle size. These components, that consist of air cap, fluid nozzleand paint needle, are supplied as a complete set. Insert paint nozzle before paint needle.5. exchanging the air piston and air piston packingTo replace the air piston remove the hollow screw and detach the air micrometer. Pull out spring and air piston Exchange the airpiston. Unscrew stuffing box screw and remove the old packing. Now insert new Packing with flat end first and gently tightenstuffing box screw towards packing.6. Cleaning and maintenancea) Flush the material-conveying parts of the gun thoroughly with thinner.b) Clean the air nozzle with a paint brush or brush. Do not immerse the nozzle in thinner.c) Under no circumstances try to clean clogged orifices using an unsuitable tool, since the slightest amount of damage adverselyaffects the spray pattern.7.lnternal nozzle pressureAt an entrance pressure of 43 psi and more at the air inlet, the internal nozzle pressure exceeds 10 psi. The maximum is stampedonto the gun body.Possible failures in operation1. Trouble: Gun leaks from fluid tip.Cause: Foreign substances between fluid tip and needle prevent sealing.Repair: Clean fluid needle and fluid nozzle in thinner or use new set nozzle.2. Trouble: Paint merges from fluid needle - needle sealing.Cause: Self tensioning needle sealing damaged or lost.Repair: Replace needle sealing.3. Trouble: Spray pattern in sickle shape.Cause: Horn air holes or air circuit clogged.Repair: Soak in thinner, afterwards clean with the nozzle-cleaning needle.4. Trouble: Drop like or oval shaped pattern.Cause: Dirt on fluid pin tip or air outlet.Repair: Turn air nozzle by 180 degrees. If defective pattern remains, clean fluid tip pin and air circuit.Back to Contents |
